Hi @ssimenhoff02 ,
Land use and density are covered in PA objectives 2.2 & 2.3. See snippet from the ARE 5.0 Handbook below.
If you have a Black Spectacle’s subscriptions the lectures on these objectives will definitely help you understand land use and density. Mike will walk through examples of how zoning regulations effect the design and type of building you can put on a site.
We also have a free video on FAR if that’s something you’re hoping to learn more about.
Beyond that, another way to get familiar with these topics might be to read local zoning codes so you become familiar with their components and how to read them.
Hope this helps!
